Dr. Battery 9-cell 10.8V 6600mAh replacement

This Dr. Battery MPL05240XP-29 is a new 9-cell lithium-ion pack rated at 10.8V and 6600mAh (71Wh). It serves as a direct replacement for numerous Dell Inspiron models including 13R, 14R, 15R, 17R, N4050, N5050, N5110, N7010, N7110 and several M-series and N-series variants. The black housing matches the original form factor for these systems.

Verify model number and voltage before ordering

Check the part number printed on your existing battery against the supported list such as YXVK2, 04YRJH, 06P6PN, 07XFJJ, 08NH55, 312-0233 or 312-0234. Confirm the original battery shows 10.8V output to match this unit. This pack is not for laptops requiring a different voltage or a 4-cell or 6-cell configuration. Buyers who need a higher capacity than 71Wh or a different form factor cannot use this product.

Nine-cell lithium-ion build

The 9-cell lithium-ion construction delivers extended runtime compared with lower-cell-count packs. An integrated smart control chip manages quicker charging, lower power consumption and longer discharge cycles. Built-in safeguards protect against short circuit, overheat and overload conditions during daily use. The battery carries a 1-year warranty from the 2006-established brand.

Questions about this item

Does the Dr. Battery MPL05240XP-29 arrive as a single 9-cell pack or do I need extra cells or a charger?

The box contains one complete 9-cell lithium-ion battery rated at 10.8V and 6600mAh. No additional cells, cables or external charger are required; it installs directly into the laptop's battery bay.

My Dell model appears several times in the compatibility list with different screen sizes — how do I pick the right one?

Match the exact model number on the bottom of your laptop (for example Inspiron 15R N5110 or 14 N4050) against the supported list. If the model matches, the 6600mAh capacity is the only version offered for this part number.

What does the 71Wh rating mean for daily runtime on a Dell Inspiron 15R?

The 71Wh capacity stores more energy than lower-Wh packs, so a typical Inspiron 15R can run longer between charges — exact hours depend on screen brightness, workload and power settings.
